Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sanitary cleaning device that performs cleaning by discharging cleaning water in a hot water storage tank to private parts of the human body.

Configuration of conventional example and its problems This type of conventional sanitary cleaning device is as shown in Fig. 1.
A toilet seat 3 and a device main body 4 are installed on a toilet bowl 2 having a toilet 1, and a nozzle 5 is provided at the rear lower part of the toilet seat 3 as a flushing water discharge means to discharge flushing water to the private parts of a person sitting on the toilet seat 2.
and a pump 6 that sucks water in the distern 1 and pumps it to the nozzle 6. Further, a hot water storage tank 7 and a heater 8 are provided as a means for heating and storing the washing water to an appropriate temperature, a sensor 9 for detecting the temperature of the washing water in the hot water storage tank, a variable resistor 10 as a means for setting the temperature, and a washing switch 11. A control means 12 that energizes the pump 6 to perform cleaning when turned on, and energizes the heater 8 in response to the input from the sensor 9 and the input from the variable resistor 10 to control the temperature of the cleaning water in the hot water storage tank. has.

FIG. 2 shows a block diagram of the control means 12 in the conventional example. 13 is a power source; 14 is a circuit that converts the value of the variable resistor 10 into a set value as an electrical signal; 16 is a circuit that compares and amplifies the set value 14 and the signal from the sensor 9, controls the heater 8, and This is a comparison amplifier circuit that maintains the cleaning water temperature at a set value. The capacity of the hot water storage tank 7 is about 11, and the capacity of the heater 8 is
The electric capacity is about eoow, and it takes about 5 minutes to heat water at 6°C to the appropriate temperature.

In the above-mentioned conventional configuration, the user sits on the toilet seat 2, moves the variable resistor 10 to set the temperature of the wash water, and when finished, turns on the wash switch 11, energizes the pump 6, and discharges the nozzle 6. Washing water in the hot water storage tank 7 is released from the tank 7 to wash the private parts.

However, in the above-mentioned conventional configuration, since a hot water storage type water heater is used, which is less likely to cause burns, the time it takes to raise the cleaning water in the hot water storage tank 7 is short and there is no problem, but on the other hand, it is difficult to lower the cleaning water in the hot water storage tank 7. It is not possible to descend immediately because it has to wait for natural heat dissipation. Therefore, if the previous user likes hot water and operates the variable resistor 10 and sets it to the highest temperature, for example, 42°C, then the subsequent user likes lukewarm water and sets it to, for example, 32°C.
Even if you operate the variable resistor 1o hoping to get 8°C washing water, the washing water in the hot water storage tank 7 does not drop immediately, and the hot washing water of 42°C is released, making you feel uncomfortable. It turns out.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and aims to make it possible to perform washing at a desired water temperature.

Structure of the Invention In order to achieve this object, the present invention uses conventional control means to fix the set value of the setting means to approximately the lowest setting value when the device is not in use, and to adjust the setting value to the lowest setting value while the device is in use. It has an added function to release the fixation.

With this configuration, the user can adjust the set value to his or her preferred value at the beginning of use, and can obtain cleaning water at the desired temperature during cleaning.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

What is different from the conventional example in FIGS. 3 and 4 is that the rear part of the toilet seat 3 is lifted up when the toilet seat 3 is not in use and the user is not sitting on the toilet seat 3, as a means of detecting when the device is in use. , a microswitch 16 is provided which is turned on by the application of the user's weight while the user is sitting on the toilet seat 3 and the device is in use, and its contacts are connected in parallel with the variable resistor 1o.

In the above configuration, when the device is not in use, the contacts of the microswitch 16 are closed, so the variable resistor 10 is short-circuited, and the set value 14 is set to the lowest value, for example, 38° C., regardless of the value of the variable resistor 10. Been waiting. When the user sits on the toilet seat 3 to use this device and immediately sets the variable resistor 1o to his/her preferred value, the contact of the microswitch 16 is opened and the cleaning water in the tank 7 reaches a temperature of 38°C. It is heated from 1 to 2 to reach the set temperature. This heating takes an average of several minutes, so there is no need to rush from the time the user sits down to the time when the variable resistor 10 is set, and by the time the user finishes and starts the cleaning operation, the temperature will be at the appropriate temperature. be. When the user performs washing, the appropriate temperature washing water in the tank 7 is pushed up by the water pumped to the bottom of the tank 7 by the pump 6, and sequentially sent to the nozzle 5 from the upper side of the tank 7 and discharged. When you stand up from the toilet seat 3 after washing, the contact of the microswitch 16 closes again, and the set value 14 is 38°C regardless of the value of the variable resistor 1o.
The entire cleaning water in the tank γ, including the water pumped from the bottom, is heated to 38°C and kept warm.

Effects of the Invention As described above, the sanitary cleaning device of the present invention has a control system that fixes the set value of the setting means to approximately the lowest set value when the device is not in use, and releases the fixation of the set value while the device is in use. Although it has a hot water storage tank-type cleaning water heating configuration that causes less burns, it can be adjusted from low to high temperatures by adjusting the set value to the value of your preference at the beginning of using this device. You can freely set the washing water temperature to your preference, making it more comfortable.
